Mr. Trump’s “style is so potent,” and has blown past ideology, Mr. McInturff told an audience at the 2016 CFO Network. Republican voters have felt betrayed by what they perceive as too much compromise with President Barack Obama’s administration and have turned to a non-traditional candidate, he said.

Mr. Trump doesn’t share traditional conservative views on trade with the rest of the Republican party and has tapped into a deeper sense of anger with government to carry the nomination, Mr. McInturff said.

Mr. Trump labeled the Trans-Pacific Partnership, which includes Japan, Vietnam and Australia, a “horrible deal,” The Wall Street Journal reported in February. He said he feared China could join the partnership and could devalue its currency to compete with other countries because currency talks within the TPP are not binding.

Hillary Clinton opposed TPP, Wall Street Journal reported in October. Ms. Clinton had previously supported the Partnership, but said then, “based on what I know so far, I can’t support this agreement.”

Mr. Trump is strongest among white male voters without a college degree, Mr. McInturff said, and weakest among college-educated women.

In an informal poll of the CFOs in the room, however, 52% said they would vote for Donald Trump while 48% backed Hillary Clinton.

Boards and C-suite executives overwhelmingly see risk as having an important role in value creation, but just 17% of respondents say they are actively using risk to drive returns, according to a new global survey from Deloitte. The survey also found that senior stakeholders want chief risk officers to spend significantly more time playing the strategist role, with a majority of respondents saying their risk officers should participate more in setting the strategic direction of the company and aligning risk management strategies accordingly.
